APPENDIX B: STATISTICAL TEST RESULTS FOR BEFORE/AFTER
COMPARISONS OF EMPLOYEE DATA

This appendix also tabulates the results of statistical tests of telecenter users, which are described in Chapter 3. Unlike Appendix A, the sample are those who responded to both the before and after versions of the telecenter user survey: the sample size is 27, except where noted. Significantly differing means at a level of significance of 0.10 are marked in boldface type. The calculation for telecommuting frequency (in terms of percent of days) given in Table B-1 is described in Table 3-10. Tables B-2 and B-3 report the mean response from a 5-point scale that runs from strongly disagree (1) to strongly agree (5).
